Public pressure for expansion of secondary and higher education has forced governments of several developing countries to urgently seek ways to meet this demand. Many of these countries have been hard hit by debt and high world interest rates. At their 1984 conference, Commonwealth Ministers of Education requested the Secretariat to examine ways to improve use of existing resources for education, and to find alternative sources of finance. To meet this request, the Secretariat drew up a program of workshops. This document is the chief product of a workshop held in the Caribbean to discuss cost-effective teaching of secondary school prevocational subjects. Thirteen chapters are divided into four sections: (1) Preliminary Issues; (2) Making Efficient Use of Expensive Components; (3) Generating Extra Resources; and (4) Conclusions. A choice is offered between two main policy objectives: whether practical subjects are regarded as part of general education preparing students for life, or whether they are considered prevocational, or even vocational, giving specific skills and leading straight into particular occupations in the world of work. Particular attention is paid to the special facilities, equipment, staffing, and class sizes usually required by practical subjects. A list of suggested readings is included. (LAP)
